How to Draw a Radius on Google Maps (Free Alternative)

7 min read

Google Maps is the world's most popular mapping app, but it doesn't have a built-in tool for drawing radius circles. If you need to see "everything within 10 miles of this point," Google Maps can't do it natively — you need a third-party tool.

Free alternative: Use SimpleMapLab's Map Radius Tool to draw circles on an interactive map with instant area and perimeter calculations. No sign-up, no download.

Why Google Maps doesn't have a radius tool

Google Maps is designed for navigation — getting from point A to point B. Features like radius circles, area measurement, and isochrone mapping are GIS (Geographic Information System) functions that serve a different use case. Google offers these through the Google Maps Platform API, but not in the consumer-facing app.

How to draw a radius circle (step by step)

  1. Open the Map Radius Tool — it loads instantly in any browser, no account needed.
  2. Set your center point — search an address, click the map, or use GPS with "Detect My Location."
  3. Set the radius — use the slider (1–500 miles), type a custom value, or click a preset (5, 10, 25, 50, or 100 miles). Toggle between miles and kilometers.
  4. Read the results — the circle appears instantly, and the stats panel shows area, perimeter, and diameter.

What can you do with a radius circle?

  • Real estate: See all neighborhoods within 30 miles of your workplace
  • Delivery zones: Define how far your restaurant delivers
  • Signal range: Visualize cell tower or Wi-Fi coverage
  • Job search: Find jobs within commuting distance
  • Emergency planning: Show evacuation zones around a facility
  • Marketing: Define a local advertising radius

Beyond circles: what else can you do?

A radius circle shows straight-line distance, but real travel follows roads. For a more realistic view of what you can reach, try these tools:

Frequently asked questions

No. Google Maps does not have a built-in radius tool. You need a third-party tool like SimpleMapLab's Map Radius Tool.
SimpleMapLab's Map Radius Tool is free, requires no sign-up, supports multiple circles, and shows area/perimeter calculations. It works worldwide.
Google Earth Pro (desktop) has a circle measurement tool, but it requires downloading and installing the application. SimpleMapLab runs in any browser.
The circle uses geodesic (Turf.js) calculations on the WGS84 ellipsoid, accurate to within meters. At high latitudes it correctly accounts for Mercator projection distortion.
Yes. Use Find ZIP Codes in Radius, Find Cities in Radius, or Population Within Radius to see exactly what falls inside your circle.
Yes. SimpleMapLab's Drive Time Map shows how far you can actually drive in X minutes, following real roads instead of drawing a straight-line circle.
